The Indiana Jones character is based on the typical fantasy adventurer model. As Indy himself says in Indiana Jones and the Last Crusade: "Forget about any ideas you had about 'lost cities' and digging up the world... Seventy percent of all archaeology is done in the library; research...reading..." In other words, if potential archaeologists base their reasons for entering the field on the Hollywood adventures of Dr. Jones, they're in for a major disappointment.
